In another study, Ezhov and Shvaljov (2015) used a laboratory-scale EVS-10/5 magnetic separator for dry beneficiation of iron ore of the Backer deposit. This was done by analysing the influence of the current strength in the electromagnet winding of the magnetic separator on concentrate yield and recovery.
**Iron Ore**: Iron ore is perhaps the most well-known example of a mineral that is separated using magnetic separation technology. Iron ore typically contains iron oxides such as hematite (Fe2O3) and magnetite (Fe3O4), both of which exhibit strong magnetic properties. Magnetic separation is used to concentrate iron ore by separating the ...
